JS不间断向上滚动,无缝滚动,图片滚动代码

<div id=demo style=overflow:hidden;height:139;width:232;background:#f4f4f4;color:#ffffff><div id=demo1><img src="http://www.lanrentuku.com/down/js/images/12460764740.jpg"><img src="http://www.lanrentuku.com/down/js/images/12460764741.jpg"><img src="http://www.lanrentuku.com/down/js/images/12460764742.jpg"><img src="http://www.lanrentuku.com/down/js/images/12460764743.jpg"><img src="http://www.lanrentuku.com/down/js/images/12460764744.jpg"></div> <div id=demo2></div> </div> <script> var speed=50 demo2.innerHTML=demo1.innerHTML function Marquee(){ if(demo2.offsetTop-demo.scrollTop<=0) demo.scrollTop-=demo1.offsetHeight else{ demo.scrollTop++ } } var MyMar=setInterval(Marquee,speed) demo.onmouseover=function() {clearInterval(MyMar)} demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)} </script>

提示：你可以先修改部分代码再运行。
